Product Description
Limited Quantity: Many of these blemishes are hard to photograph. We have not photographed these telescope tubes. If you want a pristine telescope, you should order a new one but if you do not mind a small scratch or blemish on either the tube or dew shield, this is your chance to save $500. Quantities are obviously limited. As we run out of blemished tubes this web page will change and not allow you to order. When this happens, it means we have no more blemished tubes for this model.
Delivery: Once you order, please allow several weeks for delivery. We have a number of these blem tubes and a number of completed objectives standing by with more objectives at the coating lab and on the way. The sooner you order, the sooner we can assemble, align, QC and ship yours. When we run out of objectives in house, we will have to wait for more to come from the coating lab. The other thing that will delay an order is the focuser selected. Order with a Stellarvue 3" focuser and there will be no focuser-caused delay but if you order an upgrade, those focusers are limited. It may take 30 days or more to get certain upgraded focusers. You can call us to get a more accurate estimate of a shipping date. Be aware, we are closed Thanksgiving Day and the following Friday but we will be available the following Saturday to answer emails and take your calls.
This is the exclusive, Stellarvue 5" f-8 apochromatic doublet refractor using an objective with super-low dispersion FCD100 and Lanthanum elements and carefully hand figured in our shop to ensure all aberrations are reduced to a very low level. Learn all about this here: Stellarvue SVX127D Refractor video. This video will take you behind the scenes to show you how and why we hand figure all SVX objectives.
Waiting Period: Stellarvue SVX127D Refractor's are now available. Contact us if you have any questions at (530) 823-7796 or email: mail@stellarvue.com.
- A Stellarvue 3" dual speed focuser with 4.4 inches of drawtube travel, 2" and 1 1/4" compression ring adapters
- FB finder scope dovetail mounting base.
- Large removable extensions between the focuser and telescope for wide field bino-viewing without the need for optical adapters.
- Cnc machined, heavy duty mounting rings.
- Your choice between the Losmandy style TP013A or the Vixen-Style TP012 mounting rail.
- Handle: The Stellarvue #HAN-2 handle is included.
- Precision adjustment mechanisms on both the objective lens cell and the focuser. The telescope leaves here permanently aligned but customers requested the ability to be able to precisely adjust the focuser and the objective just in case they accidently drop the instrument on a hard surface.
Tube and dew shield: The Stellarvue SVX127D comes with an aluminum tube and dew shield that is finished in Instrument White. Fittings are black anodized aluminum. The dew shield retracts reducing the length of the telescope when being stored. Extending the dew-shield minimizes dewing of the objective at night and serves as a glare shade during the daytime.
Internal tube treatment: The inside of the main tube assembly is painted "ultra flat black" and is baffled to eliminate tube wall reflections.
Aluminum hinged rings: The SVX127D comes with Stellarvue rings that are cnc machined from one inch thick 6061-T6 aluminum. There are five 1/4-20 threaded holes top and bottom. There is a center hole, two holes that are 1.5" apart and two holes that are 2.4" apart. American made Stellarvue rings are significantly stronger than cast aluminum rings.
Light gathering and magnification power: A 127 mm refractor gathers 329 times the amount of light the naked eye does. Although Dawes limit states maximum power for telescopes under good conditions is about 300 power for a telescope of this size, since this is a high Strehl apo refractor you can exceed this power on steady nights. Check the Recommended Accessories section to make the best choice for eyepieces.
Two-year warranty and Stellarvue Service: We are friends for life. Stellarvue telescopes and accessories are covered by a two-year warranty. But it does not stop there. Since we are a telescope maker, we can repair your telescope for a very nominal fee years after it goes out of warranty, should you accidentally drop it on concrete or otherwise damage it. Buy a Stellarvue Telescope with confidence. Our customer care is legendary.
Optional Accessories
In addition to the supplied accessories, you will need the following:
1. Visual Use: For visual use you will need a star diagonal and eyepiece(s). Our finest visual accessories may be purchased with the telescope at a discount when the telescope is finished (see special offers below).
2. Mount and Tripod: We recommend the following mount/tripod combinations for this telescope:
- Celestron AVX Mount/Tripod. This is a lightweight mount with a go-to computer. It is a very reasonably priced and portable EQ mount.
- Losmandy GM811G. Made in the USA, this is a precision EQ mount with computerized go-to function. If you plan to image with this telescope this is a good choice. If you only want to use the telescope visually, the less expensive GM8 version will work fine.
3. Astrophotography: To image with this telescope, you will need a photographic field flattener (SFFX-1 for SVX127D). Imaging the night sky will also require an accurately guiding mount, off-axis guider, or a guide scope with a guiding camera.
4. Finder Scope: For easily locating objects at night, we recommend our top rated 50 mm optical finder scope. To mount the finder scope, you will need our R050DA adjustable mounting rings. Our EI002 reticle illuminator will allow you to see the crosshair reticle in the eyepiece at night.
5. Optional C130SKB Hard Case. This American-made, waterproof hard case comes with a very durable die cut foam lining.
Specifications:
Objective Lens:
127 mm clear aperture, 1,016 mm focal length (F-8), apochromatic doublet using super low dispersion (SD) optical glass and Lanthanum.
Tube Assembly:
Machined, fully baffled, aluminum tube painted Instrument White outside, ultra flat back inside.
Weight:
Telescope tube weighs about 16.6 pounds. Weight with mounting rings:19.4 pounds.
Dimensions:
The main tube has a 5-1/4" diameter. The complete telescope is about 35 3/8” long with dew shield retracted and about 41 3/4" when extended. This is with the 60 mm bino-viewer extension attached. When this extension is removed, and bino-viewers are used the telescope itself is 60mm shorter. The extension is 120 mm on the 3" Feather Touch version since this focuser has a shorter drawtube.
Dew shield:
6-1/2" diameter fully retracting dew shield with cap.
Focuser:
This telescope comes with a Stellarvue 2.5" dual speed focuser with 1.25" and 2" adapters. This focuser is a fine focuser for visual use. For imaging we recommend a 3" focuser. Choose from a 3" FSV-3B Stellarvue rack and pinion dual speed focuser or a Feather Touch 3" focuser. They both come with 2" and 1.25" compression ring adapters and a finder scope mounting base is included.
Extensions to facilitate virtually any binoviewer:
The standard model with our outstanding 3" focuser comes with two large extension tubes placed in between the focuser and the main tube. One is 60 mm long and the other 40 mm long. The extensions stay in place when used with eyepieces or a photographic field flattener but when binoviewers are added along with the 2"-star diagonal, one or both extensions can be removed. This positions the focuser closer to the objective eliminating the need for additional optical correctors to enable the binoviewer to come to focus. This increases the size of the field while reducing the amount of glass between the objective and the eyepiece. This results in a brighter, wider field of view. If ordered with the Feather Touch focuser, two 60 mm extensions are provided since that focuser has a shorter drawtube.
Rings: R130 cnc machine mounting ring set with five 1/4-20 threaded holes top and bottom. Holes are spaced 1.5” and 60 mm apart respectively, with one in the center. These are not lightweight, cast aluminum but machined 6061-T6 aluminum that is far more durable than castings.
Light Gain: 330. (Human eye = 1)
Manual: A full-color, printed operator's manual is included with each telescope. Here is a PDF copy of that manual: SVX127D Manual
